Description

Display the recorded content of the screen

The present invention relates generally to computers, and more particularly to computers having the ability to capture and record screen images.

Traditionally, screen images may be captured for a variety of uses. For example, screen recordings may be suitable for business, training, teaching, manuals, websites, and education. In general, screen activity is dynamically recorded in a video format and screen activity is recorded on a hard drive for future use.

Traditionally, the application software has been used to obtain the screen recording function. These application software must be purchased and thus incur additional costs.

In some embodiments, screen recording can be performed with better security, performance, power saving, and cost by using a keyboard, video, and mouse function provided in a computer system chipset on the motherboard. There is no need for additional software to support the on-screen recording function. The video frame can be stored in the system or, in some instances, the video frame can be selectively provided to a regional network.

According to certain embodiments, the performance and functionality of the screen recording can be improved using existing chipset infrastructure or hardware in a personal computer. In the usage of this specification, a "wafer set" is one or more microchips that operate together on a motherboard to allow each computer component to communicate with one another. Thus, if a chipset solution is used in some embodiments as compared to a software solution, the central processing unit can be made to have fewer operations. Therefore, in some embodiments, the effect of power saving can be achieved. Moreover, in some embodiments, the cost of the user can be saved because the user does not have to purchase additional software that can perform screen recording.

A chipset that is part of the processor hardware and has a video frame capture function integrated into the hardware can be used to provide on-screen recording. For example, a keyboard, video, mouse (Keyboard, Video, Mouse; KVM for short) function is embedded in Intel The brand is also known as the P55 Express chipset of the Platform Controller Hub (PCH). Thus, in some embodiments, the keyboard, video, and mouse functions can be used to provide a new use for screen recording, a use not previously provided by such embedded functions.

The keyboard, video, and mouse (KVM) functions allow the user to control another computer using a remote keyboard, video display unit, or mouse, or conversely, to enable users to access multiple monitors, keyboards, Or use a single computer with your mouse. Traditionally, this KVM function has been implemented with a dedicated hardware switch, but software for implementing the KVM functionality can also be found. Therefore, it is possible to remotely control any computer. In the existing Intel In the brand chipset, the keyboard, video, and mouse functions provide encryption of the compressed data via a local area network (LAN). In some embodiments, the compressed video frame information can be stored in a built-in storage device of the same system as the chip set, and the keyboard, video, and mouse functions can be used for screen recording.

In some embodiments, the chipset keyboard, video, and mouse infrastructure stream and compress live screen activity captured via a regional network for manageability purposes. In some embodiments, the keyboard, video, and mouse infrastructure may be secure for management reasons.

The same data can be transferred to the storage device in any video format for screen recording purposes. For example, Intel The brand wafer management subsystem can transmit this functionality via a regional network. The same data can be transferred to a virtualization engine or controller for storage on a system hard drive.

Thus, referring to FIG. 1, a processor-based system 10 can be any processor-based system, in accordance with an embodiment. For example, the processor-based system can be a personal computer, a telephone, a set-top box, a server, a laptop, a video recording device, a Mobile Internet Device (MID), or any other processing based. System. In one embodiment, system 10 can include a processor core 12 coupled to system memory 16 and a graphics system 14 such as a graphics processing unit.

Processor core 12 can also be coupled to a chipset 18. In one embodiment, the chipset is an Intel P55 Express chipset supplied by Intel Corporation (located in Santa Clara, California). The chipset 18 can have a hardware keyboard, video, and mouse function 20. Therefore, the chipset includes a keyboard, video, and mouse function for providing the stored video to a local area network 22. Other examples of chipsets that may include a KVM function include, for example, Northbridge, Southbridge, Input/Output (I/O) Control Center, Platform Control Center, Integrated Memory Controller, or Memory Control Center.

The stored video can also be transmitted to a storage device 24 on system 10, in accordance with some embodiments of the present invention. In one embodiment, storage device 24 can be a hard disk drive, but any storage device can be used for this purpose.

Referring to FIG. 2, graphics system 14 generates video frame material as indicated by block 32 of sequence 30, in accordance with some embodiments. As shown in block 34, the video frame data can be stored in a memory buffer. For example, in one embodiment, the video frame material can be stored in memory 16.

Check in the diamond 35 to determine whether the KVM function or the screen recording function is selected. In some embodiments, the selection can be received from a user input device and processed and provided for execution by the processor core or even within the wafer set 18.

If the material is to be used in a manner related to a KVM function via the local area network, as indicated by block 39, the material is encrypted and compressed and transmitted via the local area network 22.

Otherwise, if the KVM function is not selected, but the screen recording function is alternatively selected, a user selection can specify a series of video frames. In other words, the user can indicate a time series of video frames that can be recorded. For example, the user can use a user interface to indicate a starting video frame for screen recording and a final video frame for screen recording. Alternatively, the user can select only the screen recording until the screen recording is closed by stopping the selection. In one embodiment, a user interface having a thumbnail of a series of video frames that the user can select for screen recording can be provided to the user. Alternatively, the user can choose whether to use each displayed screen for recording.

Thus, for example, in a sequence using a software, a plurality of display screens can be displayed. A user interface for selecting a screen record for each screen display can be provided to the user. Therefore, the screen can display a specific user interface, the screen can be recorded, provide another screen display, and if the user chooses to record the screen display, the screen display can also be recorded, and so on.

Then, as indicated by block 36, the chipset 18 (especially the keyboard, video, mouse function 20) can extract the video frame material. Finally, as indicated by block 38, the extracted video frame data can be encrypted, compressed, and stored for on-screen recording. In an embodiment, the storage device may be built into system 10, for example, in storage device 24.

In some embodiments, sequence 30 can be implemented in hardware. In other embodiments, sequence 30 may be implemented partially or wholly in software including instructions stored in a sequence of computer readable media. The computer readable medium can be any computer readable medium, including semiconductor memory, magnetic memory, or optical memory. Thus, in some embodiments, when software is utilized, the software instructions can be stored in storage device 24 or memory 16 in some embodiments.

Certain embodiments may result in lower costs for the final purchaser. Moreover, relying on the chipset moves a processor-centric solution to a chipset-centric solution, thus consuming less processing power in some embodiments. Then, in some instances, power consumption can be reduced and performance can be increased with better security.

The graphics processing techniques described herein can be implemented in a variety of hardware architectures. For example, graphics functions can be integrated into a chip set. Alternatively, a discrete graphics processor can be used. As a further embodiment, the graphics functions may be implemented by a general purpose processor including a multi-core processor.
